Hi! We just bought a new property and don't have any infrastructure yet for the chickens, so I put together an outdoor brooder shelter for my 2 batches of chickies (one batch 4 weeks, and other is 3 days). It's enclosed all the way around except one side, and my brooders slide into it (one brooder is an old parrot cage on its side, and the other is a metal battery-type brooder, just the top tier). I have heat lamps in there and I can adjust the height somewhat with them, and have tarps over the top and to flop down and close off the open side at night. But I'm still getting way too cool for the new babies (3 days old) at night and it's getting really hot during the days. It's just feeling like a constant battle to keep it reasonable for the babies (the 4-weeks seem to be doing fine with the temp swings - they're mostly feathered out anyways).
How do you guys regulate the temps in your outdoor brooders? We're in Zone 8, so getting down in 40s at night (could get into 30s but no more frosts) and up in the 70s or 80s during the day, might hit 90 in the next week or two.
